No, I have not done any data logging because with the incorrect EPROM the ECM was in limp home mode. Also, when I connected a scanner to the ALDL, I was not able to read any codes. Once I installed the EPROM you sent with the AKDX bin, the motor ran fine initially. After 4-5 restarts, the motor began to falter and struggled to idle smoothly. From that point on, it was hard to start and I could see heavy streams of fuel (not a fine mist) pouring from the injectors. I suspect one of the areas in need of some attention will have to be the idle fuel mixture.
Now with the AKDX installed, my next objective is to figure out how to data log using my AutoPROM.
You really should get the datalogging up and running for even the initial start ups. You can record it all and be able to look through the log and see most of the problems your experiencing.
I was successful in getting three data log files which I uploaded into a new thread...

After posting the data logs, it dawned upon me that when I opened TunerPro (to begin data logging) the software had loaded the last set of .bin, .xdf, and ,adx files. I had read somewhere that prior to starting data logging, there should have been a copy of an .adx/.ads file loaded.
Will having these "old" files loaded in TunerPro have an effect or in some way contaminate the data logs?
Do you recommend that I do a new set of data logs with only an appropriate .adx loaded?
Lastly, is there a way that I can extract and save the .bin file that is currently burned on the EPROM in the ECM? What are the steps for doing this task?
yes, just down load the file you sent me and have tp open it.i looked at the datalogs, put the 288 back in with the chip that went to my truck and get a data log at 185 degrezz at idle with out giving it gas and let me look at that.you can read the 232 chips but you cannot pro gram them. tuner cats has a free to try program that includes the 747 ecm you may want to look and play wit it. try pluging the data log cord I sent and see if it will be picked up by the auto prom driver.you are advancing [data logging.:happy:]
This seems to be an important piece of the puzzle. Ran fine with '288 initially then like you said the problems came after the '8625. In one of your post, I noticed you said the E-fan kicked on 200dF. The data log you posted, yeah rich and engine temp never got over 140dF. Anyway, I have a few '747s that you can try out. The only V6 one I have is missing the PROM chip so I need to make one. I'll prolly burn the one you posted in one your threads. I can also bring my antiquated laptop and see if there's anything that seems amiss. Just let me know when the next time you're gonna go play!
It was a great pleasure to put a face to a screen name!!! Don't want to steal your thunder...anyhoo drove home with 2732A in hand, (btw thanx) stuck it in my burner, did a blank check, loaded AKDX.bin, burned and verified. Next test is to stick it in my home brewed UV eraser and try it again.
how did you homebrew the eraser? I've been looking for a uv source.
Please, please, please read about the inherent dangers when dealing with UV light!!! Purchased 4W UV-C G4T5 bulb and this florescent utility light. Stuffed it in a gutted L69 ECM case and found a suitable 6v power supply (leftover from an old cell phone charger). Drilled a hole the same size as the window on the EPROM. I'll just set the EPROM over the hole, plug the cell phone charger into a power strip, turn light on w/ power strip switch and walk away for 30 minutes. Crude but it works. Once you start using EEPROMs, you'll never go back!!!
Sounds like a project. I have a few old eproms that need checked out. thanksa lot. What is the normal erase time? 15-20min.
It seems to vary as I've left them in there for 15-20min and they would blank check or not! Sometimes when they blank check alright, they don't burn correctly so I cook them longer. It's kinda annoying!!!
On second thought, stuck the 2732A into a OE PROM carrier and put it into one of my '747 ECM. You can borrow for comparison with your '747 if yours continues to not run right. BTW that AKDX.bin didn't seem to have EGR disabled.
:mad1:
OK, guess I need to learn more about what needs to be done to modify the bin...lol. I did re-solder the few pins of the ZIF that looked suspect. Once I re-burn the 28-pin with the AKDX bin, I'll install it into my modified 7747 and put the ECM into the truck. If the motor doesn't run better, I'll take you up on the offer to borrow your 7747.
I also downloaded WINALDL and installed it onto my Surface Pro 4. I was able to connect to the ALDL using my AutoProm setup and it appeared to be capturing data. However, there was a flashing RED box to the right of the CONFIGURATION tab. Also, whenever I tried to place "checks" under the FLAG DATA and other tabs, the "checks" disappeared. So, something is amiss...don't know if my setup was working correctly. I will keep fiddling with it as well as do some reading.
To turn EGR off, Open up TunerPro RT and scroll all the way to the bottom to "Patches." All you gotta do is apply the EGR patch. Once that's done, I will save as renaming it to xxxxsansEGR. Yeah, that was an incredibly fast lightning round when I showed you how to change that one VE cell that was reading rich. You shouldn't need to use WinALDL since you have TunerPro RT. Just download the right ADX file and you can use it like a scanner.
Huh, didn't realize or think of using it that way. So, just load only the ADX. The one I have is $42-1227747-V5.2.adx. I'll give it a try tomorrow.
Don’t quote me but I think you need the xdf file too.
So being I can't leave things alone, I took the 2732A back out, put it in the eraser for 30m, blank check good, deleted EGR in AKDX.bin burn and fail!!! Erased for 30m again, blank check good, burned and success!!! Soooo...even with this new 2732A, erasing with UV light routine continues to be problematic...
